Yeah, they still ended up non-stackable. I also found out that I can't ACTUALLY run the cropnalyzer with a Lapotron Crystal.
I've got a sort-of workaround, if I plant the non-stackable seeds back down, any seeds or products from THAT result are stackable. Works the same way with seedbags that the cropnalyzer doesn't want to take. Seems like a weird bug for me to have.
Alternatively, I can dump all of the products into a trans tablet and pull out regular stackables of them.
